Therapists rarely bring a dissociative client to supervision with the word dissociation in the question. What I hear instead is: why isn't this moving? She agrees with everything I say and nothing changes. He remembers our last session completely differently. Why do I feel so sleepy with this one client?
Dissociation is meant to stay hidden. That was its job. It hides from supervisors as well as from therapists, and if neither of you has trained in it, it's easy to read what you're seeing as resistance, low motivation or a personality disorder, and to push harder in a direction that makes things worse.
When to think about dissociation
Some patterns are worth taking seriously. Insight builds and nothing shifts in the client's life, or the progress from one session has vanished by the next. The client goes flat or glassy, loses the thread mid-sentence, mentions gaps in time or things they don't remember doing. They seem like a different person from week to week, or within the same hour: a different voice, a different age, a different opinion of you.
Then there are your own reactions. You feel foggy, sleepy, deskilled or fiercely protective, or you leave with a headache you didn't arrive with. In this work the therapist's body often notices before the therapist does.
What to bring
Start with assessment. Has dissociation been screened for, and how? A brief screen like the Dissociative Experiences Scale (DES-II) can open the question. A fuller self-report measure such as the Multidimensional Inventory of Dissociation (MID), or a structured interview like the SCID-D, can help answer it. Part of supervision is deciding whether that's needed, and how to raise it with the client without frightening them.
Bring whatever map of the system you have: who shows up, what each part seems to carry or protect, and who never seems to come. It doesn't need to be complete, and you shouldn't push for completeness, but working with no map at all is how therapists get lost.
Think about phase. The ISSTD's adult treatment guidelines describe treatment in phases: safety and stabilisation, then work with traumatic memories, then integration and rehabilitation. A lot of stuck cases are trying to process before the client can stay present. Others have been stabilising for years because nobody is sure when it's safe to move on.
And bring yourself. Dissociative clients can relate to you in shifting, contradictory ways, and the transference is often strong. In one session you can be the rescuer, the perpetrator and the parent who left. Your urge to rescue, your wish to pull back, the parts of you that get stirred up: all of that is useful material.
“You don't need to have all the answers about a dissociative client. You need a place to think clearly about them, so you can stay present when they can't.”
What good supervision looks like
Good supervision slows things down. It helps you work out what the system can actually tolerate, pace the work to that, and ease the pressure to fix everything at once, including your own.
It takes the parts seriously without getting lost in them. Whether you think in terms of structural dissociation, ego states, IFS or Schema Therapy modes, the aim is to work with the whole system, not only the part who books the sessions.
And it looks after you. This is long work, and it can be disorienting and lonely. Burnout and secondary traumatisation are real, and supervision is often where they're first noticed.
Choosing a supervisor
Look for someone who works with dissociative clients, not someone who has only read about them. Ask which frameworks they use, how they approach assessment and diagnosis, and how they think about risk. Ask whether they'll work with your reactions as well as the client's material. If registration or accreditation matters to you, check whether their supervision counts.
Supervision with me
My clinical work is with complex trauma and dissociation, including DID and OSDD, using Schema Therapy, EMDR and parts work. I'm on the BPS Register of Applied Psychology Practice Supervisors, and I'm a Schema Therapy supervisor in training, so if you're working towards ISST certification and have completed Part 2 of your training, ask about one of my two certification places. There's more on that in Schema Therapy supervision for accreditation.
You can bring a single case or set up regular sessions, one to one and online. If you'd rather think alongside other clinicians, there's also a drop-in case consultation group. Both are on the Therapists page.
